Grass for your cat's water bowl?
The Drinkwell Pet Fountain now comes with an "Aqua Garden" for cats. It grows a blend of wheat, oats, barley and rye that cats supposedly love to eat. The grass is said to relieve indigestion, control hairballs and protects your houseplants from Fluffy's desire to graze.
The grass is shipped in "Pod Packs", which you just toss into the blue hanging basket. When it grows and gets eaten, you toss another Pod Pack in there. This way, the manufacturer keeps getting more of your money.
